Ultraviolet Liquid Sterlization

The possibility of microbial contamination in water and other liquids long ago prompted our engineers to provide an ultraviolet product line with the principal intention of destroying bacteria and other micro-organisms in liquid. Since 1951, our team has led the way in achieving state-of-the-art ultraviolet equipment for liquid applications.

Liquid Sugar Purification Systems rely on a “thin film” design to provide an effective, sound treatment. As some liquids, such as juices and liquid sugars are opaque, it can be difficult to treat due to their low transmission, color, viscosity, and occasional higher temperatures. With our innovative thin film design, staging the lamps in a tight proximity to each other sends the liquid sweetener product to a proper disinfection range. Internal baffles are also common in these systems to create turbulence inside the vessel, adding to the resonance time and enhancing ultraviolet germicidal output.

Process Water

Successful treatment of water and other transparent liquids with UV depends on a number of factors, such as clarity, absorption of ultraviolet, amount of suspended matter, flow rates, temperature and, of course, the type or kind of microbial contamination. The transmission characteristics of UV on liquids is dependent on the depth of the liquid, as well as the absorption coefficient of the liquid. Ultraviolet intensity through liquids decreases logarithmically with the distance from the lamp along with the absorption coefficient further relates itself to the presence of minute traces of iron compounds and organic matter.

Our commercial and industrial lines of Liquid Purifiers will provide a minimum dosage of 40,000 mw/sec/cm2. Each Liquid Purifier is manufactured in various sizes to accommodate different flow rates for a “single pass through” or a recirculatory system, as in industrial storage tanks, hot tubs, spas and swimming pools.

Residential systems are small scale versions of our industrial line that use a special UV lamp to target and disable harmful waterborne disease causing microorganisms (pathogens).

Over 100 years ago, scientists found that when pathogens were exposed to UV light, their reproduction was limited. The light resided in the UVC range of the spectrum. Specifically, they discovered that light in the 254 nanometer (nm) range was the most effective. When exposed to UV light, their cells become damaged and this inhibits reproduction. UV light damages the cell’s DNA and RNA and once damaged, they are unable to replicate and therefore, rendered harmless.

Rain Water Harvesting

With the use of ultraviolet germicidal energy in rain water applications on the rise, the need for cost effective, “green” methods have been aggressively pursued. Some areas of use in a green environment where UV may be beneficial is showering, washing of clothes or even drinking, dependent upon the type of system in the line process.

Considerations for ultraviolet use include, effective pre-filtration and routine testing. Ultraviolet lamps must “see” the target microorganisms in order to effectively destroy them. Large and even small scale particulates can deter the performance of the UV rays by masking bacteria. Proper pre-filtration methods can remove these particulates, allowing the lamps to operate at their full potential. In the event that water is trapped or near a contaminated source, it is crucial to test the quality of the water on a continuous basis.
